尚、この様な作業に関しては、当業者の間で広く一般的に行われているものであり、詳しく言及した特許文献などが無いため、先行技術文献を開示できない。 FIG. 11 shows a state when the gas meter 12 is attached to the existing gas pipe 11. As shown in FIG. 11, the gas meter 12 is between two gas pipes 11 (a gas inflow pipe and a gas outflow pipe) that are installed side by side with a predetermined interval so as to rise upward from the ground. Installed.
On the end side of the two gas pipes 11, there are provided an opening 14, a cap nut 15 having an internal thread formed on the inner peripheral surface thereof, and a flange portion 16 to which the cap nut 15 can be locked. A gas pipe union joint 18 (hereinafter referred to as a union joint 18) is provided so that 14 opens downward.
When the gas meter 12 is attached, the cap nut 15 of each union joint 18 is screwed into two caps 13 each having a male screw portion formed on the outer periphery thereof, whereby the gas meter 12 can be installed at a predetermined position. it can.
In such a union joint 18, when the gas meter 12 is attached, it is necessary to check the mounting state of the rubber packing 19 set on the seal surface 16 a of the flange portion 16 and to clean the opening portion 14.
It should be noted that such work is widely performed among those skilled in the art, and since there is no patent document or the like that has been mentioned in detail, prior art documents cannot be disclosed.

しかしながら、袋ナット１５がフランジ部１６に係止した状態においては、袋ナット１５によって、ゴムパッキン１９や開口部１４が覆われてしまうため、ゴムパッキン１９の装着状態の確認や、開口部１４の清掃作業を行う際は、それらが良く見えるように、作業者が袋ナット１５を手で持ち上げながら行わなくてはならず、煩わしいものであった。
本発明は、上記実情に鑑みてなされたものであって、ガス配管用ユニオン継手におけるゴムパッキンの装着状態の確認や、開口部の清掃作業を簡便に実施し得る袋ナット保持具を提供するものである。 However, in the state where the cap nut 15 is locked to the flange portion 16, the rubber packing 19 and the opening portion 14 are covered by the cap nut 15, so that the mounting state of the rubber packing 19 can be confirmed and the opening portion 14 can be checked. When performing the cleaning work, the operator had to do it while lifting the cap nut 15 by hand so that they could be seen well, which was troublesome.
This invention is made in view of the said situation, Comprising: The cap nut holder which can implement the confirmation of the mounting state of the rubber packing in the union joint for gas piping, and the cleaning operation of an opening part easily is provided. It is.
